Sea Sagas of the North interweaves prose chapters and alliterative sagas. Each chapter tells of travels across shores, seas and islands. These are heroic crossings in warming waters. Each saga tells of tales and times from across the ages. Icelanders ask, "How do we say goodbye to a glacier?" This is the territory of sagas, the Norse and Anglo-Saxon gods of old, and the mythic era of Viking expansion by clinkered longships. It was when dragons protected people from themselves by hiding gold and silver hoards.

These crossing tales and sagas begin at elemental wilds of north-west Iceland. They take in the Lofoten Isles of Norway, Sj land and the resund in Denmark, cross the sea to the eastern shore of England, and travel to the north lands of deepwater ports, inland abbeys and the holy shore of Lindisfarne, and then to the Atlantic isles of Shetland and St Kilda, and wind-torn fragments of the Faroes, completing the circle back at Iceland's fire and ice.

The book reaches its conclusion with the saga of the Drowning of Doggerland and how the once-dry steppe was flooded by the warming seas, making the people of the plains refugees. The book finishes as Ragnar
